Crossing,laser irradiation and recurrent selection were used to breed near isogenic lines of ’Jijing 88’.Through phylogentic analysis,identification of resistance to rice blast,rice quality inspection and analysis of yield traits,11 stable and resistant near isogenic lines of ’Jijing 88’ were got and they were tested by a group of experiments and demonstration.The results showed that combination planting of near isogenic lines could effectively reduce the harm of rice blast and increase the yield.This will extend the application time of super rice,make full use of the potential yield of super rice,and maintain a high level of yield of rice per unit area.
